this is error log ![屏幕截图 2026-02-06 151846](https://canada1.discourse-cdn.com/flex009/uploads/comfyui1/original/2X/8/8a9ef4eb9f5aa5d87444a2c84a0ae103598570ee.png) It worked fine before, but it has been unusable since version 0.8.1. The issue may have been caused by my updating the NVIDIA graphics driver. I tried uninstalling and reinstalling PyTorch, and the results are as follows: (ComfyUI) H:\ComfyUI.venv\Scripts\>pip uninstall torch torchvision torchaudio comfy-kitchen -y WARNING: Skipping torch as it is not installed.

Personally, I would just gather up your inputs, outputs, models, custom nodes and workflows in a folder and just uninstall the whole thing then delete comfyui folder completely in documents folder and the ones in app data. Then reinstall with the latest version to make sure everything is there. Starting fresh is way faster than tracing down things unless you enjoy the challenge and the hope of connection with an empathetic female and not a femboy like myself. But if your into that, then your plan worked​🤣 If not just delete everything including this conversation and it’s like it never happened. But I will cherish this time spent just integrating self-deprecating comedy with IT and riding off into the ether… 🖖 ---

i go even so far that i don’t do update anymore, i simply reinstall Comfyui when there’s a new version and i need the new features. Updates usually breaks things and makes it worse with ever further update. I cannot recommend it.
